New 2015 Shimano XTR 1x11

It's hard to say. The website in OP's post definitely looks bogus. But saying that, Shimano has been doing 11-speed stuff on their road bikes for at least a couple years now, so it's only a matter of time before that technology moves over to mountain bikes.

With a 1140 you loose at most three quarters of gear in respect to 1042. with 1142 you are almost identical. (Reason is that 11 to 10 is a very small gap, 1042 is actually a bit of silly idea).

I would have preferred that Shimano came out with 1142 10 speed, but because I am migrating from 9 speed 1140 eleven speed will do just great. For people that do not mind a dual ring a 1140 cassette with, say, 26 and 40 chain ring offers a massive range.

And you would think every manufacturer would make servicable cassettes, but they dont.

That's a different discussion, but I personally don't have a need for seviceable cassettes. By the time one cog reaches the end of its life, others will be close behind. I'd rather just replace the whole cassette, chain and maybe chainring(s) together. That being said, I don't use cassettes like the XTR with titanium cogs that tend to wear more quickly.

I looked more closely at the literature that was posted and it says the Hollowtech II crank arm is "compatible with all of the new XTR chainrings." So, it looks like they will be replaceable.

You are so consistently wrong on your XX1 pricing Davide - Nobody pays MSRP - Srams XX1 can frequently be picked up for $900 ish. Knock off the $hit about $1500.

And yes, $900 is still expensive, but at least stay accurate. I know ya got it in ya.

Maybe you can tray to say something interesting for a change? I put a range of $1000-1500, it all depends where/when you buy and if you need to buy an extra wheel. The low end of my range is actually $100 away from your claim so what's your point ...

The post was about the new Shimano more than anything else, if the rumor is true I am a bit disappointed about the 11 speed which I think is useless, but happy about the 1140 that is a very nice set up and plenty range-wise, with a dual ring and Di2 it will be huge for the people that need it.

But I also think that it is good to reiterate that $1000-$1500 spent on SRAM in 2014 gets you a system that has no advantage in respect to 1142, and has just a tiny bit more range in respect to 1140. Things have changed since last year when you only had 1136 as an alternative to 1042, and SRAM really looks like a silly waste of money.
